Worst Panic Attack Ever

(USA)

It was during the summmer of last year, I was out at a store and I started to feel uneasy out of nowhere. When my mom and I arrived at home, I started to feel that sense of unreality like I did not know what was going on. I also had a really nervous stomach ache and I was extremely lightheaded. I felt like something really bad was going to happen. I also felt like I was going to pass out. My heart was beating really fast. I felt a tingling sensation in my hands and my head. My legs felt like jelly. I couldn't eat or drink and nothing could stop it. Finally, after a few minutes, I told my mom to take me to the emergency room. There, I told them my symptoms and they checked my heart and everything and told me there was no emergency. They said it was an anxiety/panic attack. It sure felt like something else. They gave me a huge cup of ice water to sip. I felt a lot better but I started to avoid going places due to this.
